Best Pulse Oximeter You Can Buy Right Now
Stay informed about blood oxygen saturation and pulse rate
Given the current scenario across the world, where new coronavirus cases are emerging every second, and people are asked to maintain social distancing to control the spread of the coronavirus (COVID-19), it has become more crucial now to stay informed about the health condition of your own and the closed ones. While most of us abide by the “use mask when in public” and “sanitize and wash hands frequently” measures, the growing number of cases and the lifting of the lockdown is something that still rings warning bells every time we step out of our house.
One way, for some people, especially those with underlying morbidity, is to use something like a Pulse Oximeter to stay informed about the blood-oxygen saturation (SpO2) and the pulse rate. However, much like hand sanitizers and face masks, two of the most sold and in-demand products for the past few months across the world, Pulse Oximeters are also hard to get these days. To add to that, there are a plethora of brands and options to choose from, which makes things even more confusing. So, to make buying easier here’s a list of some of the best Pulse Oximeters you can get online.
What is an Oximeter?
Before we begin, here’s a quick primer on Pulse Oximeter: a Pulse Oximeter is a device that relies on Pulse Oximetry — a noninvasive method that provides information about the oxygen saturation in your body and the pulse rate. Being noninvasive, the method does not involve surgical procedures to carry out the tests. Instead, it requires a device, called the Pulse Oximeter, to be placed on a thin part of the body like a fingertip, earlobe, or toe.
Once placed on one of these body parts, the device relies on transmissive pulse oximetry, in which it passes two wavelengths of light (red and infrared) through the body part to a sensor on the other side of the probe. Now, depending on how saturated is your haemoglobin (present in the blood), it absorbs different amounts of light. And the sensor, on the other side of the probe, determines the same by reading the amount of light absorbed. In addition, the device also shows the pulse rate, which can change depending on the blood saturation levels, among other reasons.
With the coronavirus (COVID-19), one of the symptoms happens to be pneumonia — a condition that results in lungs being filled up with fluids. As a result, the heart struggles to maintain an adequate level of oxygen, and eventually ends up with high levels of carbon dioxide within the body, leading to severe complications and the need for external oxygen supply. To avoid this, one of the ways that some of the doctors suggest is to use a Pulse Oximeter, which helps you determine the blood saturation levels and pulse rate instantaneously. Especially, if you (or your closed ones) happen to have underlying morbidities, the device can come in handy to keep a check on the two parameters, to look for warning signs — if, any.
